Mainly graphics, like Vulkan, NVIDIA, Mesa
And everything that Wine & Steam needs for 32-bit support
Using 18.04 in a container as a base seems to be only a band-aid solution in a massive hole that was created. I was skimming through Wine’s mailing list, and it seems that while you are working with Valve on making sure none of our games from Steam break, they stopped recommending and supporting Ubuntu.
And we need those 32-bit libraries for legacy applications and games.
Say we run Steam and Wine in a container, and we purchased a new, unreleased as of now, Radeon GPU that most likely won’t be supported in 18.04’s kernel, like Radeon RX 5700. IIRC, even the latest AMD GPUs, like Radeon VII, don’t even work well with 18.04. What happens then? Would we still be able to run our games and applications there? What happens when 18.04’s support ends?
I was also reading the Ubuntu Developer mailing list, and it seems that this will negatively affect flavors, like Ubuntu Studio.
